2.5l or 4.0 radiator power mod

So my 2.5l has the dreaded radiator leak around the crimp. I'm planning on replacing it, and have found an option for $50 more and includes an electric fan. From what I have read (on the net) is you can gain 10-15 hp by converting to am electric fan and removing the oem fan, shroud and putting In a radiator with an electric fan. Anyone done this and does it work? Is it worth the $50 to convert?

I dont see how it would give you that much gain when it's just making your alternator do more work. But if it does that would be sweet. I dont think there's any easy way to add HP short of a stroker, small turbo or super charger.

Back to topic I would go OEM radiator all the way. The aluminum is surely made in China and wont last.

I've had multiple Drake offroad aluminums in the last 8 months. To the point they are paying for the shipping so they can have it back and refunding my money. I don't think any of these other radiators are actually more efficient. Even if they have a lifetime warranty let me tell you first hand it sucks waiting for the replacement and then putting it in. Over and Over. Especially in Montana winter. Outside

My two cents. I just ordered a new one from Wermopar. gets here tomorrow

I have had extremely good luck with everything I have put an electric fan in, more mpg, bump in hp, and much quieter overall engine. The reason you get a gain is because the fan only runs occasionally when stopped. mechanical fans run all the time, even clutch fans don't help much with this. you would be hard pressed to find one in a brand new vehicle. Winter time with the heat blasting it will almost never come on. Use a good thermostat/relay kit and make good weather tight connections(like the factory does), adding a real temp gauge is good idea too, and you wont have any prob's.

Did you just add a fan to the stock radiator? Or new radiator and fan? I'm going to try to crimp my stock one today. And see if I can help it out without buying a new one for 200!

My sons 2000 is now leaking around the top crimp on its 2nd Spectre (Autozone) radiator in the past 2 months. WTF ? Is there something I'm missing with these radiators ? It has a new 18lb cap and it opens and closes as it should. Just put this 2nd rad in 2 days ago and it was fine. He goes out and starts it up this morning to let it warm up and when he went out to leave it was pissing from the top crimp.

Ive had enough of messing with this mother fu**** . I dont care what it cost I want a radiator that will hold. Open for all suggestions.

Anyone try the USA made Griffin ? http://www.quadratec.com/products/51210_2101_07.htm

Anyone have any luck with the radiator barn all metal 2 row ?

I think all these plastic tank radiators are a awful design. A solid all aluminum radiator works well, why stray away from it? Dumb designers...

An electric fan not only saves power by remaining off until it is needed, it also operates at the necessary thermostatic speed independent of engine speed, which is one of the biggest drawbacks of a belted fan. Combine these two factors and you greatly improve the engines efficiency and that equates to better power and MPG. Pair it with a good thermostat and solid connectors and it should do fine.

IMHO, the only valid reason for installing an electric fan is if you need to shut the fan off for deep water crossings. It certainly doesn't boost HP in a significant amount since the electric fan's added load on the alternator will make the alternator harder for the engine to turn it. I've known too many desert wheelers who tried electric fans but gave up to go back to mechanical fans that can easily pull a lot of air through the radiator after their engines started running hotter from the electric fans.
